Question

product of x and y is equally to the product of 540 and 784521.lf x is equally to 45 find the value of y. ​

Answer 1

Answer:

x>y

Thus, x−y=5 and xy=24

x−y=5

Squaring both sides,

=>(x−y)

2

=5

=>x

+y

−2xy=25

=>x

2

+y

=25+2(24)

=>x

2

+y

=73

Now,

(x+y)

2

=x

2

+y

2

+2xy

=73+2(24)

=73+48

=121

=>x+y=

121

=±11

Given, x and y are positive numbers,

Therefore, x+y=11
